At how many electron-Volts is light absorbed by glass?
« on: 23/05/2016 22:37:25 »
So the electron energy levels in glass, the exact number in eV that allows transmission of light through solid matter like glass, and some transparent plasics.
Is this number in eV known to science, like it takes 13 eV to move the hydrogen electron to the next shell level.
So the energy level requirment in electrons in glass would be less than 13 electron voltsvolts when light hits the electron wouldn't it, that's why it does not absorb light, and transmission happens.
Is this correct.
I am grateful for you help, anything helps even a few words. [:D]

Yes.

Most glass begins absorbing light significantly at about 350 nm and below (that's 3.5 eV). Very high purity fused quartz is transparent down to about 200 nm (6.2 eV).

It's more complicated than that. Xrays- with thousands of eV go through stuff.
